SILO-DOOR FBAIME.

Application filed August To all whom. it may concern Be it known that I, Cnsrnn M. E. Boos, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Silo-Door Frames, of which the following is a specification.

My invention relates more particularly to a frame having provisions for holding and permitting adjustments of the ends of stay wires or rods used in the construction of tile silos and the like, and aims more especially to produce a structure of the character stated which shall be easy, simple and economical to manufacture; to provide a frame which shall have convenient means for the vertical adjustment of stay vires; to produce a structure convenient to use; and. such further objects, advantages and capabilities as will later more fully appear.

My invention further resides in the com.- bination, construction and arrangement of parts illustrated in the accompanying drawing, and while I have shown therein a preferred embodiment I desire the same to be understood as illustrative only and not as limiting my invention.

in the accompanying drawing:

Fig. 1 is a plan view of one of the embodi ments of my invention.

Fig. 2 is a broken perspective view of the construction shownin Fig. 1.

Fig. 3 is a broken plan view showing a different kind of slide for holding the ends of the stay wires.

Fig. 4 is a view similar to Fig. 3 showing another form. of the holding means.

Referring: more in detail to the annexed drawing, letter F represents the frame and D the door, provided with a door locking means L. The frame F comprises a plurality of upright members 1, 2, 3, 4., secured together in pairs by means of spaced brace members 5. Members 1 to 4 inclusive are preferably pieces of steel angle irons, perforated. for the reception of bolts 6 or the like, which may permit a limited amount of adjustment in order that the side members of the frame may be made precisely parallel and adjusted to exactly the right distance apart. As shown, the locking members L are secured to the door sections D and have a part 7 which may be rotated in the base portion in order to permit the door section to be locked in place.

Serial No. 497,167.

it is obvious from an inspection of the drawing that the pairs of members 1, 2 and 4.- are spaced sufficiently far apart to permit the holding members 8, 8 or 8 to be received. and slide freely therein. These forms illustrated are simply some of the forms which may be used in this connection, but those shown in Figs. 3 and i are considered preferable to the one shown in Fig. 2. If theframe is to be used with narrow tile, angle irons 1 and 2 will be brought closer together by the use of stay irons 5 of proper length and distance between the perforations forthe bolts 6, whereas if wide tiles are to be used the angle irons must be placed. farther apart and it will then be preferable to use the double angle irons, as shown in Fig. 4, in preference to the T irons shown in F ig. S. Secured to members 8, 8 or 8 are the ends of stay wires or rods 9 as shown in the various figures.

Secured to the inner faces of the inner angle irons by suitable means, as bolts 10,. are facing strips 11 of non-metallic material, the purpose of which is to keep the contents of the silo from coming in contact with the angle irons 2 or 4. The manner of securing these strips to the angle irons is immaterial and I have merely suggested theuse of bolts for this purpose.

It will be observed that smaller angle irons 12 perforated and secured to angle irons 2 and 4L by means of bolts 6 or otherwise. These angle irons 12 serve as abutments for the door sections D to rest against, thereby furnishing effective means for preventing the door sections from. being forced outwardly by pressure from within.

It is also to be noted that with the form of holding member 8 shown in Figs. 1 and 2 it is possible to secure a certain amount of adjustment of the length of the stay wires 9, by varying the position of the nuts on the hook-members.

.t will be evident from the drawing and the foregoing description that I have provided a frame which is simple and economical to manufacture and easy to use, and one in which it is easy to secure proper vertical adjustment of the stay rods 9.

Having now described my invention, I claim:

1. In a structure of the character described, a frame comprising pairs of spaced members of predetermined lengths connected to said angle-irons for holding the angleirons a given distance apart to provide for adjustably connecting stay means in the pairs oi angle-irons, and stay means ad- ;iustably connected thereto.

2. In a. structure of the character described, side members held at a given distance from each other, each side member comprising a pair of angle-irons spaced to form a. slot for the reception of a staynvire holding member, and means to hold the angle-irons at a given distance apart. I 3. In a structure of the character described, side members held at a fixed distance from each other, each side member comprising a pair of angle-irons, means to hold the angle-irons at a. fixed distance apart to form a slot therebetween, and stay- Wire holding means adjustably slidable in the slot between the angle-irons, and stay- Wires connected to said holding means.

4:. In a frame, pairs of oppositely placed spaced angle-irons, spaced brace members connecting the members of the pairs of angle-irons at fixed distances apart, brace rods connecting the pairs of angle-irons at substantially fixed distances apart, and stay- Wire attaching members extending through the slots between the angle-irons and slidable vertically therein.

5. In a structure 01 the character described, side members held at a fixed dis tance from each other, each side member menace comprising a pair of angle-irons spaced to form a slot for the reception of a stay-wire holding member, means to hold the angleirons at a fixed distance apart, and other angle-irons secured to opposite ones of the first named angle-irons to form door rests.

6. In a structure of the character tescribed, a frame comprising pairs of spaced angle-irons, space members connected to the angle-irons for holding them in spaced relation to form a guide slot therebetween, in combination With non-n'ietallic facing strips secured to the inner faces of the inner angleirons.

T. A frame comprising a pair of side members, means adjustably holding the members of each pair in given spaced relation, stay means being adjustably connected to and between said men'ibers, and means holding the pai s of members in spaced relation.

8. A frame comprising corner members, means holding said members in spaced relation, means slidably adjustable in the space between said members and connect ed to said members in adjusted positions, and stay members connected to the slidably adjustable means.

In witness whereof, I hereunto subscribe my name to this specification.
